Improvement in water-wheels

JOEL SANDFORD, OF POLO, ILLINOIS.

IMPROVEMENT IN WATER-WH EELS.

Specification forming part of Letters Patent Nol 45,755, dated January 3, 1865.

To all 'whom t may concern Be itl known that I, JoEL SANDFOED, of Polo, in the county of Ogle and State ot' lllinois, have invented a new and Improved Water-Vheel; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part ot' this specitication, in Which- Figure lis a side sectional view of my invention, taken in the line w 00, Fig. 2, Fig. 2, a horizontal section ofthe same, taken ill the line y y, Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to a new and improved horizontal Water-Wheel; and it consists in a novel construction ot' the buckets, as hereinafter set forth, whereby it is believed that a large percentage of the power ot' the water is obtained.

To enable those skilled in the art to fully understand and construct my invention, I Will praceed to describe it.y

A represents a circular plate, which forms the bottom of the Wheel, and B is an annular plate or rim, which forms the top ofthe wheel. O are the buckets, which are placed in a "ert-ical position between the plates A and B.

The buckets G are formed as follows: The plate A, which is the bottom ofthe Wheel, has its periphery divided into a number of parts, corresponding to the number of buckets designed to be used. These points of division are indicated by c, and b represents radii extending from the points a, to the center a of the plate. (See Fig. 2.) The backs ot' the buckets C are formed of two ditt'erentcnrved surfaces-one, c, being a part of a circle described from a center, el, which is at the centers of the radii b, the parts c extending from the points c to a circle, e, which intersects the radii b two-thirds of their length from the eenter ot' plate A. The inner sides, j', of the buckets C are a portion of a circle, the center f/ of which is 0n the radii b, one-third of their length from the center ot' the plate A, the sides f extending from the inner ends ot' the parts c to the periphery of A. The other parts g of the backs of the buckets extend from the outer ends ot' the same to the outer ends ofc, and coincide with the periphery ofA. By this arrangement it Will be seen that the spaces between the buckets gradually contract from their inner to their outer ends, the issues It being the narrowest part, and hence the water in passing outbetween the buckets acts upon them the whole distance of their length.

It is designed that the number ot' buckets in all cases should be in accordance with the size of the Wheel and the supply ot' Water thereto, so that the combined areas of the issues h will be less-say, from one-fourth to one-siXth-than the area ofthe Hume through Which the wheel is supplied with Water. By this means the water cannot escape through or between the buckets Withoi'ltkproducin g the e'ect desired.

I d0 not claim, broadly, constructing the buckets of waterwheels ot' curves irrespective ot' the manner of forming the curves, as described; but

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A Water-Wheel, constructed with buckets (j, each formed of three arcs, described from the several centers d f af, all as herein shown and described.

JOEL SANDFORD.
